It is my understanding that while you can't search for the user in the
typeahead for "Equals" you can type the user's name in the open field
that appears when you've selected "Contains" in the prompt. That said,
I'm still upvoting this request because I need Deactivated users to
function no differently than my Active users for the purpose of reports,
searchability, etc. We've resorted to downgrading their access from Plan
to Reviewer so our data isn't affected.
